Disk cleaner?

some of my ps2 games are scratched up but not that badly, they freeze during gameplay, does anyone know anything that i can do or use to fix my disks to playable condition? thanx in advance

EDIT: o snap i just realized that i posted this in the wrong forum. sorry..

try staples i think i saw some disc cleaners there they undo all the scratches...but that was about a year ago december wen i got my new comp that i was last there

thnx, staples is pretty far away from my house tho.. ill look everywhere i can
